Intrinsic property simulation
« on: June 07, 2021, 07:17:31 PM »
Hello, if there is no visible porosity that is able to be resolved during imaging (for example of the microporous layer) is it possible to still include an inherent porosity to be used in a diffusion simulation for combined GDL/binder/MPL? I am able to determine the fine porosity using other methods and would like to include it in the global simulation. Thanks!

Hi Robin,
to enter an intrinsic porosity of a material phase into a diffusivity simulation, use the Simulate Diffusion Experiment -option.
In the Edit-menu you can now enter the effective values either in terms of effective diffusivity or in terms of effective porosity and tortuosity.
Together with the material parameters of the other material phases, GeoDict can thus calculate the resulting diffusivity for the entire structure.
